In the Android & iPhone/iPad game “Temple Run,” the last upgrade for each of the four powerups costs 25,000 coins. These are listed:

Allow disabling Mega Coin.

Allow disabling Coin Magnet.

Allow disabling Invisibility.

Allow disabling Boost.

What do these upgrades do? Should you buy them?

These upgrades give you the option of turning OFF whichever powerup you bought the upgrade for. That means you won’t see it appear in actual gameplay. Once you get the “Allow Disabling…” upgrade, you can always turn the powerup back on if you choose. The Store will allow you to freely switch between enabling or disabling the powerup at no additional charge.

So why would you want to turn any of the powerups off? Well, the Mega Coin for example doesn’t give you all that many coins. For that reason, I disable the Mega Coin so I can get one of the other, more powerful powerups more often.

Also, if you are focusing on one specific objective, for example, the “10k Runner” to run 10,000 meters, you may want to enable ONLY the Boost powerup and leave everything else disabled. That way, all powerups you find in the game will be Boosts, and you can get a better run distance.

Finally, if you want to collect the most number of coins possible, you need to disable every powerup aside from the Coin Magnet, like I describe in my earlier blog post here.
